SOIL-WORKING. IMPLEMEN'I.

Application led'uly 5, 1927, Serial No. 203,639, and in Denmark Tilly` 13,v 1926.

This inventionrelates to a device for use in connection with such soll-working implements and machines as hoes, horse-relies,

harrows, weeding machines, and the like, the respective tool being attached to an arm or the like, and this arm attached adjustably to a wheeled trame, the arrangement being such that the tool can be caused to enter or cut, etc. more or less deeply into the soilA I attain the object in view, viz the adjustability of the soil-working tool, by attaching the arm carrying it to the trame of the implement or machine by a bolt upon which said arm can be turned, and'by eonnectinganother point of the tool-carrying arm with an adjustable bolt connected with a bow connected in turn with that part of the frame to which the said arm is hinged. rlhis latter is adjusted together with the tool by adjusting` said boltjrelatively to said bow, and after the adjustment the tool-carrying arm can be iixed in its new position by means ot another bolt carried by the framepart concerned and passing' through a slot in the arm, as is all more fully described hereinafter. K i

rlihe invention is illustrated diagrammati cally and by way of example on the accom panying drawingl on which it is shown in side-view, the weeding tool being shown in vertical section.

On the drawing, 8 denotes aweeding tool which is aiiixed to a curved arm 2 attached movably to a member l forming a part of the frame which is wheeled, as usual with weeding and many other agricultural machines. The arm 2 and said member 1 are connected with each other by a bolt 4 on which said arm can be turned, and the arm 2 is connected, furthermore, by a bolt 8 with a vertical adjustiucg` bolt 7 extending upwardly and with its threaded free end pass ing through a bow 9 affixed to the member i, lThe threaded end ot the bolt 7 is pro vided with two nuts l() and il, by means et which it can be adjusted in the bow 9 and secured in its adjusted position. rIherel is also a bolt 5 which is also located in the member l and passes through a slot 6 of the arm 2. .This bolt is also provided with nuts not shown) by which the arm 2 canV be clamped :tast after the adjustment so that it is secured in a twotold manner and cannot give way when the tool 3 overcomes the resistances it encounters in its path. i y

An adjustable :fasteningr device for a soilworking implement. comprising, in combina tion a downwardly extending arm carrying the respective soil-working implement, a bolt by which said arm ishinged to a rearwardly extending part of the implement trame, a bow secured to said part, an adjusting,Y and fixing bolt hinged at one end to the said arm andeXtending' with its other end which is threaded through said bow, nuts locatedA upon said threaded bolt end, and separate means forsecuring the said arm with its tool in its adjusted position substantially as and for the purpose set forth.
